The present invention relates to a pharmacologically valuable new benzophenone derivatives having a pronounced sedative action on the central nervous system and some of which also possess muscle-relaxing and aggression-inhibiting properties. These new derivatives have the structural formula R2R2 N-CO-CnH2n-N-CmH2m-R3 and their acid addition salts, in which R1 and R2 are substituents selected from the group consisting of hydrogen, saturated and unsaturated alkyl groups having 1-4 carbon atoms; R3 is a substituent selected from the group consisting of -CN, -CONH2, -COOCH3, -COOC2H5, -COOH, and -COOMe, where Me is a metallic cation; n is an integer selected from 1 and 2; and m is an integer selected from 1,2, and 3, and wherein the rings A and B may be substituted, ring A being substituted preferably with a halogen such as chlorine or with nitro, trifluoromethyl, methyl, methoxy or methylmercapto, preferably in the 5 position, and ring B being preferably substituted in the 2' position with chlorine or fluorine. The radicals R1 and R2 preferably signify hydrogen or a methyl group, or a n-butyl group in the case of Ring B.
